Deagon
At 2.82 square kilometres with 3,773 residents, Deagon sits in the northern bayside corridor of Brisbane as a compact, detached-house suburb where 87.9% of dwellings are separate houses, well above the national average. The median house price is estimated at $471,000, placing it in the affordable tier compared to inner-Brisbane markets. Household income sits at the 52.8th percentile nationally, exactly middle ground. The suburb scores decile 6 on both IRSAD and IRSD, meaning moderate advantage relative to the rest of Australia. Rents grew 20.7% over the decade while real incomes rose 18.7%, two trends that nearly offset each other and explain why rent-to-income at 21.8% remains below stress levels.

The $471,000 median house price makes Deagon more accessible than many Brisbane suburbs, and the mortgage-to-income ratio of 26.6% sits below the conventional 30% stress threshold. Separate houses account for 87.9% of the stock, with 3-bedroom homes dominant at 43.4% and 4-plus bedroom homes making up a sizeable 27.6%. The ownership split leans toward mortgage holders at 41.3% compared to outright owners at 28.4%, a sign that the suburb attracts active buyers rather than long-settled debt-free households. Average household size of 2.3 persons is slightly below the national figure. Monthly mortgage repayments average $1,846. Semi-detached and apartment stock together account for only 12.2% of dwellings, so buyers seeking a house face a market where that product type dominates.

For Investors
Deagon's 30.3% renter share supports a steady tenant pool, and weekly rent of $350 against a $471,000 median implies a gross yield around 3.9%, above many comparable bayside markets. The vacancy rate stands at 6.4%, elevated compared to the national average, which warrants monitoring before committing. Development activity recorded 22 applications in the past 12 months, reflecting moderate local construction interest. Annual population growth of 0.82% adds roughly 33 residents a year, with both internal migration (net 25 annually) and overseas arrivals (net 16 annually) contributing. Rent growth of 20.7% over the decade demonstrates sustained rental demand despite the higher vacancy rate. The suburb scores decile 6 on IRSAD, positioning it in the moderate-advantage band where tenant quality and stability tend to be reliable.

Demographics
Deagon's median age is 42, which is 2 years above the national figure, positioning it as a relatively mature suburb. Overseas-born residents account for 19.3%, some 2.3 percentage points below the national average, consistent with the predominantly Anglo-Celtic ancestry mix: English (1,591), Irish (554) and Scottish (474) lead the ancestries. University qualifications reach 31.1%, roughly 1 point above the national rate, indicating a modestly higher-educated workforce than the typical Australian suburb. Average household size of 2.3 is marginally below the national norm. The couples-with-children household type is the largest family group at 1,141, while couples without children account for 25.4% of families. Volunteering sits at 13.9% of residents, and 6.2% of the population (223 people) need assistance with daily activities.

Outright owners at 28.4% trail mortgage holders at 41.3%, suggesting a cohort of buyers who entered the market in recent decades rather than an older settled population. Renters at 30.3% form a meaningful third of households. Separate houses dominate at 87.9%, with apartments at 7.5% and semi-detached at 4.7%, giving the suburb a strongly detached suburban character. The bedroom breakdown skews toward family-sized homes: 3-bedroom at 43.4% and 4-plus at 27.6%, while 2-bedroom at 18.8% covers the smaller household segment. The median house price of $471,000 produces a monthly mortgage repayment of $1,846, and the mortgage-to-income ratio of 26.6% stays below the 30% stress level. Rent-to-income at 21.8% also remains comfortable, so neither owner-occupiers nor tenants face acute housing cost pressure at current levels.

Economy & Employment
Healthcare is the top employer at 17.3% (225 workers), followed by Construction at 12.4% (162) and Education at 12.0% (156), then Public Administration at 10.4% (136) and Professional/Tech at 8.2% (107). This mix of service-sector work aligns with the suburb's decile 5 IEO score on education and occupation, which sits at the national median rather than in the advantage or disadvantage tails. Full-time employment runs at 66.6% of employed residents, with 1,160 full-time and 582 part-time workers. The unemployment rate is 5.4%, above the national average for the period, partly because the participation rate of 58.4% is moderate and 977 residents are outside the labour force. Personal weekly income averages $831 and household income sits at the 52.8th percentile nationally.

Transport to Work
Car dependence is pronounced at 82.0% of commuters driving, while 9.1% use public transport and 3.8% walk or cycle. This is higher car reliance than the national average, consistent with a lower-density bayside suburb without a dense rail or bus network. The suburb sits at decile 6 on IRSAD nationally, the moderate-advantage tier, meaning it ranks above the bottom half of Australian suburbs on combined advantage measures. No schools are recorded inside the Deagon boundary in the current dataset, so families rely on schools in adjoining suburbs. No crime statistics are available for direct comparison. Rent-to-income of 21.8% and mortgage-to-income of 26.6% both sit below stress thresholds, making the suburb financially manageable for most households. The volunteering rate of 13.9% and the 6.2% needing daily assistance paint a picture of moderate community engagement.

EstablishedDeagon is an established suburb growing at 0.82% a year, adding around 33 residents annually. The population reached an estimated 4,034 in 2025 and medium forecasts project 4,196 by 2031, a 4% increase over six years. Over the past decade, population rose 8.9%, and the 10-year trend shows a balanced migration mix: net internal arrivals of 25 a year and overseas arrivals of 16 a year, rather than one dominant driver. The gentrification score is 4 out of 100, classified as not gentrifying, which means the suburb is unlikely to see rapid price appreciation driven by demographic change. Affordability improved from 51.0% in 2011 to 42.1% in 2021, a meaningful shift that reflects either real income growth of 18.7% outpacing rent and price rises or changing household compositions. Resident stability is high, with 78.3% staying in the same area over the measured period.

How to read these comparisons
Phrases like "above the national average" reference the unweighted median across Australian suburbs with more than 1,000 residents, not population-weighted national figures. Suburb-level medians are more useful for ranking suburbs against each other; ABS census headlines are population-weighted (so dominated by Sydney and Melbourne) and can read very differently.
Current baseline (refreshed 2026-05-10): median age 40, university-educated 30.1%, born overseas 21.6%, average household size 2.5 people.
Data sources: ABS 2021 Census (demographics, income, tenure), state Valuer-General (house prices), Department of Jobs SALM (unemployment), ACARA (school ICSEA), state Crime Statistics agencies (offences), council DA portals (development applications). Population forecasts use a Hamilton-Perry cohort model calibrated to ABS ERP.
